DSD Mode: The relationship between the oversampling ratio of the DSD audio data and the required
Master Clock to DSD data rate is defined by the Digital Interface Format pins.

De-emphasis Control (DEM1:0) BITs 3-2.
Default = 0
00 - No De-emphasis
01 - 44.1 kHz De-emphasis
10 - 48 kHz De-emphasis
11 - 32 kHz De-emphasis
Function:
Selects the appropriate digital filter to maintain the stan-
dard 15
s/50 s digital de-emphasis filter response at 32,
44.1 or 48 kHz sample rates. (see Figure 17)
Notes: De-emphasis is only available in Single-Speed
Mode.
7.2.4
Functional Mode (FM1:0) BITs 1-0
Default = 00
00 - Single-Speed Mode (30 to 50 kHz sample rates)
01 - Double-Speed Mode (50 to 100 kHz sample rates)
10 - Quad-Speed Mode (100 to 200 kHz sample rates)
11 - Direct Stream Digital Mode
Function:
Selects the required range of input sample rates or DSD Mode.
